228120-19-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 228120-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,1,2 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 228120-19:
(8*2)+(7*2)+(6*8)+(5*1)+(4*2)+(3*0)+(2*1)+(1*9)=102
102 % 10 = 2
So 228120-19-2 is a valid CAS Registry Number.

Efficient synthesis of 11-cis-retinoids

Borhan, Babak,Souto, Maria L.,Um, Joann M.,Zhou, Bishan,Nakanishi, Koji

, p. 1172 - 1175 (2007/10/03)

The light sensitivity and unstable nature of 11-cis-retinoids makes them ideal visual chromophores in nature. The synthesis of 11-cis-retinal analogues is of paramount importance in bioorganic studies of rhodopsin, the photoreceptor of the visual transduction pathway, but the instability of 11- cis-retinoids complicates their synthesis and there is no general synthetic route. Common strategies to the cis geometry have failed in the case of 11- cis-retinoids, and most often low yields and complex isomeric mixtures are obtained. Herein we report an efficient, general, and mild preparation of 11- cis-retinoids by semi-hydrogenation of 11-yne-retinoid precursors with Cu/Ag- activated zinc dust.
